Abstract (en)
[origin: US2010288119A1] A brake servo whose valve piston has a concentric sealing seat which projects axially beyond a second sealing seat, with the concentric sealing seat having at least one recess for throttling the air volume flow. The controllability and also the noise characteristics of the brake servo can be improved in this way.
